expect实现scp ssh自动输入密码登录

expect是一种自动交互语言，能实现在shell脚本中为scp和ssh等自动输入密码自动登录。
下面给出scp和ssh的使用示例：
1、scp

 expect -c "  spawn scp root@1.2.3.4:/root/1.log /root  expect {    \"*assword\" {set timeout 300; send \"password\r\";}    \"yes/no\" {send \"yes\r\"; exp_continue;}  }  expect eof"

2、ssh

#!/bin/bashexpect -c "spawn ssh root@192.168.1.204 \"ls;\"expect {    \"*assword\" {set timeout 300; send \"password\r\";}    \"yes/no\" {send \"yes\r\"; exp_continue;}      }expect eof"
